UNITED STATES PATENT GEORGE .W. PASSEL, OF CINCINNATI, OHIO.

PRESSURE-BAR FOR PLANlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 401,299, dated April 9,1889. Application filed November 26, 1887. Serial No. 256,282. (Nomodel.)

To all whom it may concern;-

Be it known that I, GEORGE W. PASSEL, a citizen of the United States,residing at Oincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Pressure-Bars forPlaning- Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention is an improvement in pressure-bars for planer-s; and I haveherein described one form of the same, and illustrated it in theaccompanying drawings.

Figure 1 is an isometric view of a pressurebar. Fig. 2 is a transversesectional view of the same. Fig. 3 is a front view, and Fig. 4 is afront view of a modified construct-ion.

The pressure-bar A is provided on its front side with a shoulder, a,below which is attached an elastic plate, 13, which is made to conformto the shape of the lower part of the pressure-bar. This elastic platemay be composed of as many pieces as desired, and is rigidly butadjustably secured to the pressurebar by bolts or screws, as shown inFigs. 2, 3, and 4.

The construction of parts is such that a short distance from the pointof attachment the elastic plate or plates 13 are held away from thepressure-barA and extend a little to the rear of the lower point of suchbar. The

plate or plates B conforming to the shape of the bar A adjacent thereto,as before stated, when said plates are pressed up against the bar A theywill fit closely against the same. The lower edge of the bar Aisunbroken and the bar is provided with a channel or series of channels,0, along the same, which are open at tact, and they communicate with thespace between the bar and said plate.

The said pressure-bar is held in position in any desired manner. Iprefer to so mount it that it shall have a movement in a curved linenearly concentric with the cylinder. The elastic plate gives a yieldingbearing-surface to the pressure-bar, readily accommodating itself to theinequalities of the material with which it comes in contact.

What I claim, and desire to secure by Letters Patent, is-

1. A pressure-bar for planing-m achines, pro vided with an inclosedchannel or channels open at one end to receive and at the other end todischarge chips, shavings, and like substances, substantially asdescribed.

2. A press Lire-bar for planin g-machines, having an unbroken lower edgeand a channel or channels for receiving and discharging chips, shavings,and like substances, substantially as described.

3. The combination, with a pressure-bar for planing-machines, of anelastic plate attached thereto, and an open channel or channelscommunicating with the space between such plate and the pressure-bar forthe escape of chips, shavings, and like materials, substantially asdescribed. In testimony whereof I affix my signature in the presence oftwo witnesses.
